T0 @ZZ whom it may concern.-

Beit known that we, CHAsLnsNwHoLs and JAMES W. SPENCER, citizens of the United States, residing at Seymour, county of New Haven, State of Connecticut, have invented a new and useful Fountain-Pen, of which the following is a specification.

This invention relates to. certain improvements in fountain-pens.

Fountain-pens as ordinarily constructed may be divided into two classes, which we will term, for convenience, vwithdrawing and non-withdrawing pens-that is, a class of pens in which when not in use the pen-carrier, pen, and feed are withdrawn into the barrel, thereby greatly shortening the pen as a whole and rendering it very much more convenient for carrying about in the pocket, and a class of pens which we have termed non-withdrawing pens, in which the pen-carrier, pen, and feed do not withdraw into the barrel when not in use, and consequently the pen as a whole is considerably longer and less convenient to `carry about. Heretofore, so far as we are aware, in withdrawing-pens-that is, pens in which the carrier and feed have longitudinal movement and maybe withdrawn into the barrel when not in use-the construction has been such as to rendera front shut-oif-that is, a shut-o in front of the penimpracticable, so that it has been necessary to carry may be placed.

the pen with the carrier and feed upward, so as to prevent leakage, and the danger of leakage in transportation when filled has been a serious objection to this class of pens.

Itis one-of the objectsof this invention to provide a fountain-pen of the withdrawing type which shall be provided with an eective front shut-oil?, so that in carrying it 4about in the pocket or in packing it for transportation when filled it is aV matter of no consequence whatever in what position the pen A further obgect of theinvention is to provide a fountain-pen of the withdrawing type having a cap adapted to actv as a screw-cap and shut-oi when applied to the front end of the barreland as a slide or affriction-cap when applied ,to the rear end or butt of the barrel and used to `projector withdraw the carrier, pen, 'andrfeed.

A further object ofthe invention is to provide a fountainpeu 0f the withdrawing type having an open-end spiral made independent of the carrier and a carrier adapted to receive any ordinary feed and any ordinary pen. The feed and pen may be easily taken out, if required, for cleaning or other purposes.

With these and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combinations, which will be hereinafter described and then specifically pointed ont in the claims .hereunto appended.

In the accompanying drawings, forming part of this specication, in which likechar- Y acters of reference indicate the same parts, Figure 1 is a lon gitndinal section on a greatlyenlarged scale, of our novel pen in the closed position, the carrier, pen, feed, and spiral appeering in elevation; Fig. 2, a similar View showing our novel pen as in use, the carrier, pen, and feed being projected and the cap in position on the rear end' of the barrel; Fig. 3, a section on the line 3 3 in Fig. l; Fig. 4, a view of the slotted sleeve detached; and Fig. 5 is adetail sectional View of the carrier detached.

A denotes the barrel, which is ordinarily made slightly tapering at both ends, and B the tip, which is securedthereto by a screwthread 10.

C denotes the pen-carrier, D the pen, and E the feed. The carrier is provided with a socket 11' to receive the feed and with a shoulder 12, against which the butt of the pen rests. Any ordinary style of feed and any ordinary style of pen may be used. The carrier is also provided with a shank 13, having a lug 14, which is adapted to work in a slot Vor groove 15, formed in ahqllow or tubular member 15,', and also within the straight slot 16 in a sleeve 17, which fits closely in the barrel, so as not to turn therein. The spiral groeve 15 and straight slot 16 are open at theirforward ends, whereby the lng le may be readily inserted in or withdrawn from said groove and slot. The member 15 is provided with a shank 19. The`- barrel is ordinarily formell with a solid head and. then drilled to make a hole 20, through which shank 19 passes, then reamed to leave a shoulder-21, against which the hase of the spiral rests,and then reamed again to IOC form a shoulder 22, against which the. end of triey sleeve'rests. The object in providing shoulder 22 is lo prevent sleeve 17 from heing pushed to the extreme inner end of the 5 nai-rel and permit a hook to he inserted and passed over the inner end of the sleeve to Withdraw it from the barrel, it being understood, of oourse, that this sleeve fits the n0rmai inner diameterof the barrel, whiehoomio prises the ink-reservoir 23.v Slot 16 in the sleeve does not ordinarily extend quite tothe inner end thereof, so as to leave at the inner end a perfect ring, as at 24. In the rear end or lmtt of the barrel We form a recess 25 to receive a suitable packing 26, as a cork, through which shank 19 passes and may turn therein, but which eiectually prevents the escape of ink at that end of the pen. Outside of ree-ess 25 is a shoulder 27 to receive a en oorresponding hub on a head 28, which is rigidly secured to shank 19, as by a drive t. Head 2S is shown as made slightly tapering to correspond with the general contour of the rear end of the barrel. It should be noted,

f, however, that at the point of Contact of the head with the end of 'the barrell the head is ot' slightly-greater diameter than the end of the barrel, as at 29, to adapt it to be engaged with a frictional Contact bythe slightly-flar-y ing open end 30 oi" the cap li', as in Fig. 2, so that the cap, head, and spiral may be rotated to project or Withdraw the carrier, pen, and feed, as will be more fully explained. ln the elosed position, as in Fig. l, the daring open of the cap receives the barrel and entne surface thereof freelyat a distance :from the iront end. At theinner end ofthe sap is rigidly secured a plugBl', having a shouider of reduced diameter and a thread- 4o ed portion 33 oi still smaller diameter. This threaded portion is adapted to engage a oorresponding internal thread at the outer end the tip, and shoulder 32 forms a perfectlyiight eonnection with an accurately-beveled inoiine at the outer end ofthe tip, the external diameter of the tip being slightly greater than the diameter ot the shoulder, so that the shoulder Will pass Within the open end. Thisis in order to avoid danger of leako age should the edge ofthe tip become slightly 'bruised or chipped.

The operation of our novel penis brieliy as follows: Suppose the pen to he in. the closed position, as in Fig. l. f The operator removes the cap hyturning it backward, disengaging the threaded portion of the plug from the thread at the outer end of the tip. He then places the oap on the rear end of the pen, the open end ot" 'the oep engaging head 28 with a friotxonal Contact, so that by turning the oag) forward the .head and the spiral Will be rotated and through the engagement of lug 14 on the shank ot the carrier with the spiral and also with the straight slot in sleeve 17, 55: as olearly shown in both Figs. l and 2the r. and with it the pen and feed, will be propelled from-the position shown in Fig. l

to the operative position, as ing of course immaterial Cap is detached from head i is in' use.' When through usi' operator turns the sap, with it head 2S and the spiral, h through the engagement of lng spiral and the straight slot r .u pen from the operative position, as in l 2, into the barrel, as in Fig. l, the oper then removes the cap from head 253, plee over the frontend of the barrel ti.. the threaded portion of the ping inte en a ment with the internal thread in the e the tip until shoulder 3l iiaeed engagement with incline at the o.. tip, as in Fig. l, thus fo.: frontshubo for the init, so be placed in any position with-enf' leakage.
